Typescript definition of filter missing argument

[oraknabo]

I have an Interactions.OlInteractionSelect with a filter. In an older version (2.0.1), it was allowing the feature to pass like below:

const selectInteactionFilter = (feature:any) => {
  return feature.values_.name !== undefined;
};

After upgrading, I'm getting the following error:
Type '(feature: any) => boolean' is not assignable to type '() => boolean'.

on OlInteractionSelect.vue.d.ts(23, 5), this is how the filter is defined:
filter?: (() => boolean) | undefined;

Shouldn't the definition include passing a filter argument through to the function?

It's happening in VSCode, not related to OS or Browser, but I'm using:

• OS: Manjaro Linux
• Firefox & Chromium
